You can run, jog or walk your way to the Sky Garden in this stair climbing challenge – whatever you feel most comfortable doing.
Your friends and family are welcome to wait in the Sky Garden at the Walkie Talkie to see you cross the Tower Climb finishing line.
Everyone is welcome to stay in the Sky Garden after their Tower Climb challenge to enjoy the stunning views of London.
Help with fundraising your stair climb
Everyone taking part in Walkie Talkie Tower Climb is asked to fundraise a minimum of £250 in sponsorship for Great Ormond Street Hospital Charity. This money will be used to help build a world-leading, child-focused Children’s Cancer Centre at Great Ormond Street Hospital, where more children can have the best chance and the best childhood possible.
When you sign up, you will automatically be set up with a Funraisin fundrasing page. Get in touch with the Tower Climb team if you would like any fundraising materials or need any advice.
Your registration fee goes towards the cost of putting on the Tower Climb event.
Why we need you
Your registration fee goes towards the cost of putting on the event, and all funds raised will help build the new Children’s Cancer Centre at GOSH and save more lives.
We need a new home to for breakthrough treatments, so we can save more children’s lives. And because cancer shouldn't get to steal anyone's childhood, we need a place that's more than a hospital – a place that's a school, a playground, a garden and so much more.
That’s why we’re building a world-leading, child-focused Children’s Cancer Centre at GOSH, where more children can have the best chance and the best childhood possible.
Together, we can build it. Together, we can help beat childhood cancer.
